Abstract

A wirelessly powered flexible tag configured to be in contact with a substrate is provided. The tag includes a coupling layer configured to couple the tag to the substrate. An electrical circuit disposed on the coupling layer and configured to interact wirelessly with an external stimulus. The tag further includes at least one electrode or at least one heating element in operative association with the electrical circuit, and configured to generate electrical energy or thermal energy, respectively. Upon wireless interaction with the external stimulus the tag is configured to induce an electrical response, a thermal response, or a combination of both in the substrate.
